I really enjoyed this puzzle. It was my first Production puzzle, and i iked it for the same reasons i like the Height Metric. Figuring out what to do in which box and slowly grinding away, improving each box instruction by instruction, Arm by Arm, was incredible. The best part about this solve is the Cursed Ratio. Twice as many of the bottom products are produced as the top product. The Bottom Product needs to be made every 2 periods because of Arm 5, and the Top Product needs to be made every 4 periods because of Arm 3. All in all, I am extremely happy with the design and am quite confident with the quality of this solve. ^^
